COTTON GIN.

Application inea April 11,`

To all whom t may concern:

Be it known that I, ROBERT S. WHEELER, a citizen of the United States,and resident of Grenloch, New Jersey, have invented certain new anduseful Improvements in Cotof which the followingis a specilication.

My present invention relates to improvegins and has among its objectsthe following:

First to provide a gin that kwill not cut, break, or otherwise injurethe fiber of the cotton in anyway, but on the contrary will improve thestaple by giving a liber the full length it grew.

Second to secure a all trash and dirt.

Third to provide apparatus that is portable, and may be used inconnectiony with a cotton picker, such for example asshown in myUnitedStates Patents Numbers 922,647 and 1,001,720; to ginthe. cotton as fastas it is picked, delivering the Vseed into one regin that will removeVoeptacle and the lint into another, or into a press on the same truckthat carries the motive power, thus doingvthe eXtra work of ginningwithout the expense of any eXtra labor, or time and very little morepower.

Fourth to provide a gin that will clean the lseed under allV conditions,cleaner than itis now done. l

Finally to provide a gin of low cost,sim ple and requiring little powerto operate.

With these and otherobjects in View the invention includes the novelfeatures of construction and arrangementiand combination of partshereinafter described and particularly Adefined in the Vappended claims.

An embodiment of my invention isA illus- Y trated in the accompanyingdrawings, in which,

Figure l is a side elevation.

Fig. 2 is an end view.

Fig. 3 is a plan view.

Figs. 4:, 5 and 6 are views of details. Fig. 7 is a detail view of cardclothing.

Referring by reference characters to this drawing A designates a pipe bywhich the cotton is conveyed from a suitable source to a hopper B, whereit comes in contact with an endless traveling surface of card clothwhich may conveniently be in the form of an endless belt C passingaround the drums CandC2. j l f As the cotton is carried by the belt fromSpecification of Letters Patent.

Patented llay 18, 1920. 1919. serial No. 289,250.

thehopper it passes beneath a plurality of presser .feet D whichinsuresl its being brought into irm contact with and attached to thebelt. From these presser feet the cot# ton is carried by a plurality ofbreasts or rows of seed arresters E. These are diago nally arranged feetor short bar members which may be conveniently suspended by verticalrods or bars member W.

The first seed arresters are set higher above the belt than thosefollowing and are so located as to allowthe seed, while thickly coveredby cotton, to be pulled under them.

The following arresters are set closer to the surface of the belt sothat the seed must pass around them, and they are also placed at agreater angle to the line of travel of the belt, so that as the seedsare cleaned andthe card cloth or belt loses its hold on them theyarresters will push them faster toward the edge of the belt. n

The arresters therefore have a carding action as each arrester onlyslightly checks the seed that strikes it, giving it at the same time alittle roll or push away from its line of travel while the lint that isfast on or adhering to the belt continues on in a straight line. Eachtime, therefore, that a seed is checked, no matter how slightly, a partof its lint is gently pulled off right at the seed which is the weakestplace and the lint is not broken or cut but preserved in its fulllength.

One or more sets of wire arresters G or brushes are provided atsuitablevpoints on the gin-belt to prevent cotton, line trash or smallseeds from bedding down into the card cloth and thus missing the seedarresters, and also to prevent clogging of the a gin belt, as they willhold back the cotton and allow only just what the card clothwill graspto go through, and Vin this vway every seed' will be acted upon by thearresters. f

At the inner end of the belt is provided an apron H, or final trash andsmall seed arrester, Vwhich is set at a suitable angle across the ginbelt. The trash and seed from which the lint has been removed, will bepushed upon this andthe air blast from air pipes P (Figs. l, 2 and 3)will blow them into seed trough L, from which they may be removed byconveyer pipe M, containing conveyer screw N, and deposited into a sackor other receptacle (not shown).

F from the top frameV he lint is removed from the cardy clothing belt,or gin belt, by a doffer brush I of any suitable construction from whichit is thrown by centrifugal force into box J, and removed throughconveyer pipe by an air blast to a press or other receptacle on 'thetruck (not shown). 4

Beneath the gin. belt is a table S or bric ge to prevent it from saggingor in any way getting away from the arresters so that they will not actproperly. This table isrepresentative of any 'suitable supporting means.

A tightener pulley Q, may be used onV gin belt, if desired, with springsIl, l, to give it the proper power. i e

The bearings that carry the-pulley C are mounted in movable bearings andprovided with adjusting screws and springs T, T, (Figs. 1 and 3) to keepthe gin belt at proper tension. These bearings, also the ones for thepulley C2 are made easily removable, so that the gin belt may be removedwithout trouble.

.A power shaft U and gearing V, (Figs. l, 2 and 3) are shown as examplesof suitable means for driving the drum C and brush and the seed conveyerscrew N may be driven by a flexible shaft O, from end of shaft thatcarries pulley C2.

What I claim is:

l. In combination an endless moving gilining element, means for feedingcotton to' be ginned thereto, and a plurality of successively locatedstationary arresters arranged in proximity to the surface of saidelement, said arresters being oblique to the line of travel, eachsuccessive set of arresters being of increased Obliquity.

2. In combination an endless moving ginning element, means for feedingcotton to be ginned thereto, and a plurality of successively locateddiagonally arranged arresters located in proximity to the surface ofsaid element. f

8. In combination an endless moving ginning element, means for feedingcotton to be ginned thereto, and a plurality of successively locatedstationary arresters arranged in proximity to the surface of saidelement, the succeeding arresters being nearer tothe surface of theelement than the preceding ones.

4t. In combination an endless moving ginning element, a hopper forholding cotton in contact therewith.y presser means for pressing thecotton onto the surface of said element, and a plurality f diagonallyarranged arresters in proximity to the surface of said element. Y f

5. In combination an endless moving ginning element, a hopper forholding cotton in contact therewith, presser means for pressing'the'cotton onto the surface of vsaid element, and aplurality of diagonallyarranged arresters in proximity to the surface of said element, andaseed and trash collector at the side of said element.` V n .6; Incombination anlendless moving ginning element, a hopper forholdingcotton in contact therewith, presser means for pressa ing thecotton onto the surface of said eleinent, and a plurality of diagonallyarranged arrestersin proximity to the surface of said element, and acollecting apron acting on said element after it has passed thearresters.

7.
